AVFloatDSPContext Struct Reference

Multiply a vector of floats by a scalar float and add to destination vector.

Source and destination vectors must overlap exactly or not at all.

Parameters:

dst result vector constraints: 32-byte aligned

src input vector constraints: 32-byte aligned

mul scalar value

len length of vector constraints: multiple of 16

Calculate the product of two vectors of floats and store the result in a vector of floats.

Parameters:

dst output vector constraints: 32-byte aligned

src0 first input vector constraints: 32-byte aligned

src1 second input vector constraints: 32-byte aligned

len number of elements in the input constraints: multiple of 16
